I don’t know if I am jealous of your new friendship with her or not.
But I feel like I am losing you
Losing my best friend
Since you befriended her I see our friendship fading away
You always spend time with her
I feel left out
She took my space as your best friend
The friendship we had is slowly fading away
I know it’s selfish for me to say 
but I am jealous of every happy memory you make with her
I don’t know if this is a sign of our ending friendship
If it is
Know I will always be by your side whenever you need me
